Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.Abstract The hypothalamic–pituitary–gonadal (HPG) axis coordinates reproductive function and incorporates gonadal sex steroid feedback to regulate gonadotropin secretion in a homeostatic manner. In females, ovarian estrogens and progestins act as the primary negative feedback signals to suppress luteinizing hormone (LH) release, whereas in males ...

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.Ethanolamine plasmalogens increased LH pulse frequency. GPR61 was expressed in GnRH neurons and gonadotrophs, suggesting a role in neuroendocrine regulation. Ethanolamine plasmalogens (EPls), but not choline plasmalogens (CPls), may act via GPR61 expressed in GnRH neurons in the preoptic area and in anterior pituitary gonadotrophs.

Seminal Extracellular Vesicles as Molecular Modulators of Male Reproductive Function
Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT Extracellular vesicles (sEVs) contained in seminal plasma (SP) maintain, in concert with free SP‐components (proteins, hormones, cytokines, metabolites and antioxidants) under an endocrine umbrella the functional in vivo homeostasis of ejaculated spermatozoa. The sEVs define a generic mixture of nanovesicles delivered by male epithelial cells,

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT This study directly compares hCG and buserelin as ovulation‐inducing agents following eCG‐based superovulation in weaned donor sows, focusing on their practical impact on ovulation‐embryo synchrony under field conditions. Fifty‐five multiparous sows received 1000 IU eCG 24 h after weaning and were treated at onset of estrus with either 750 IU ...
